Quite, and some vendors give you some very interesting 'tales'guru_1071 wrote: though of course, they can often only work with what the seller tells them!!!!
However, i would like to point out that (as noted above) the auctioneers definition of what constitutes a 'barn' is fairy flexible! it's all about making the most for the vendor, and selling the dream.
My former employers did on one occasion display a Dino with a hay-bale and a stuffed fox to convey it's barn find status. Successfully, if i recall.
barns can of course offer very good storage conditions, or amongst the worst, but the term is based more on picture postcards and jigsaw box images that in reality.
Personally, i like to see all of the old fractors on Ebay sold as 'barn finds'.
As to the Mini - you're dammed if you do and dammed if you dont in terms of restoration. Will be interesting to see if it sells.
Still, think of it's value if broken for parts on Ebay.......
